Zetec to st170 spec? - Ford Forums - Mustang Forum, Ford Trucks, Ford Focus and Ford Cars

Just out of interest...anybody have and ideas as to how hard it would be to get st170 type power from the zetec without forced induction? and would it be cheaper just to turbo? what would it take do you think?

Well, from talking to infocus motorsport and a local motorsport mob here, it would be easily done under 2 grand. Allowing a grand for a full exhaust, a couple hundred for a pod ram filter, and the remainder on a computer chip, you'll easily pull another 30 kW from the car. And that's being generous with prices, if you look around and bargain for a deal. Go with a 65mm throttle body for even more, the sky is the limit. Well, to an extent... LOL

cheers, thats what i was thinking. i know herrods motorsport are designing a full exhaust/headers setup at the moment. i'll be interested to see what sort of results they get with that. add a chip and induction....maybe as you say even the throttle body....should be sweet. hmm....sounds like a plan.

Yeah, it's something I am working towards before hitting a turbo onto the system.

I beleive it is very possible to make a better Focus than the ST170 while spending alot less. And more custom and personal, too...

Cheers...... Tim

Yep exactly what I am planning to do as well. 10k price premium for the ST170 seems too excessive.

Herrod exhaust and headers, $30 simota ram pod situated behind a bonnent vent for cold air and, chip, maybe the 65mm throttle body and bigger intake pipe and were are laughing.

by the way a $30 simota ram pod will be just as effective as a $200 uni filter

I take it the power of the ST has you. Get some tyres too while your at it. Give it extractors and some room to breathe, nice electronics and youll be fine buddy. Warrenty is bye bye though. The power you normally see at 5k rpms youll see at 3k with a decent chip.

I guess you would chose the ST170 over the Zetec for one major thing - insurance. Having gone through modifying a car to very basic levels (exhaust, rims, suspension) insurance companies take you for a ride, and sting for doing ANYTHING outside their guidelines.

But then I have special fleet discounts (about $4K off) for an ST170 so I can see your pain.

Using the nice motor the ST170 has you can strap a nice full exhaust and air filter keeping the mods simple and you have a real sleeper on your hands. If that gains (if your lucky) 20kw in total for a small outlay then you are looking at 147kw - turbo induction on a Zetec will leave little change from 10K, not to mention having to upgrade the motor's components to handle the forced induction (depending on how much boost you want to crank on to the motor), plus to be on the safe side upgrade the brakes, wheels/tyres and suspension to cope with the increase power.

So now you are already up to the ST170 level, without the trick interior, up to ST170 levels with expense and your insurer is going to point and skip around you and laugh quicker than you saying "full comprehensive insurance". Even a full exhaust on an ST170 will almost match turbo levels (not necessarily the torque, and that shove in your back, depending on how much you want to fry your front tyres!) but for a standard car with little effort you can have something pretty quick, and you can't exactly go screaming around the streets these days - you would be pretty happy with the outcome. And by the way you won't have as much stress, wear and tear, and maintenance with an NA motor as well. Factory turbo set ups are better engineered and have much more tolerance and are designed to cope with the stresses all in a standard setup. Thats why such things as the XR6 turbo are a great car to modify if you want the extra urge without the extra pain.

Well thats my opinion anyway, would be happy to hear what others have to think. This is just going from my research and experience so always willing to learn!!!

So now you are already up to the ST170 level,.....

I think after 10k on a Zetec t-kit you would be more than "up to the ST170 level"

A decent kit will do a high 13 pass with stock internals. So roughly 170kw @ front wheels Im told.

I hear what your saying though.

Hi, has cyn11c see the exhaust on the ST170. The Headers are huge. The exhaust is probably as good as you can get with only 2 small boxes out to the rear. I don't believe any changes here will give much of an increase. I could be wrong, but I have not seen any mention of alternative systems in Europe that are worth using. I would not even suggest using any Aussie made system, as they would not have a clue what they were doing on a car like this. The system has been tuned to get the most from this motor already, thats why they cost lots. Another comment on modifying the Zetec by fitting a Turbo, I don't believe that the standard motor will cope without a major rebuild to handle the extra stress. Also as I have said before the insurance will not cover you. Just think what the consequenses would be if you wrote someone off with your car. Look at rebuilding the engine at least possibly every 10K with a Turbo, & breakages with gearboxes & drive train. I get the same stress thinking about how much rebuilding a ST170 motor could be one day, with the extra stresses with the high lift cams on the Valve guides, & crankshaft & rods, pity about the poor Astra Turbo & Toyota which would be worse off.

The old Modified RS2000 needed a rebuild every 10k on the head as the valve guides used to ware out. Stripped a few gear box drive shafts, broke a couple tailshafts, & lots of busted diffs. It had 155BHP at the flywheel, & 122BHP at the wheels back then. The steel celica box fixed some of the problems along with welding the diff gears up. The ST is 170BHP & straight off the showroom floor. Want more power, buy the XR6, you won't be dissapointed. Want more buy the new DJR V8.
